@bobwyman @hrheingold @blinry @datasniff is simple to use:

1. Install from store

2. Visit a hyperlink that denotes an #HTML, #JSON, #JSONLD, other #RDF doc types (e.g., #RDFTurtle, #RDFXML), #CSV, #RSS, or #atom

3. Click on "doggie" icon and it will sniff out the structured data and present property-sheet based UI

Once the #StructuredData is sniffed out, you can download to your filesystem, #WedDAV or #LDP compliant #DataSpace (or Solid Pod), or a #DBMS (or store) that supports #SPARQL.
